Tecno A7 buggs

Hi,
I don't know english very well, please be tolerant.
I have a Tecno Phantom Z A7 that got 3 problems after changing its ROM:
- Invalid IMEI
- When I activate the WiFi it write "NVRAM Err 0x1"
- The big worry, it bugs very often and starts again itself

I don't know what to do so I need your precious helps.
Please help me Hovatek.
Thank you for advance.

I am going to try the first two solutions.
But for the last one, I already tried it and that had not solved anything. Can I have another proposition ?

Hi,
When I was trying to fix Invalid IMEI and NVRAM Error, I noticed that I must have the IMEI and the MAC address of my WiFi card. But I don't it. Is there a possibility to fix that without knowing the phone's IMEI or MAC address?

It should be attached to you phone at the back or if you remove the back cover
